To all whom may concern:

` Be it known that I, GEORGE D. Dn'MnrRo! vices.

, Some of the objects oi theY invention are; to produce a device of the character Vmentioned with which individuals upon the payment of a nominal fee may compete with each other in a submarine race which will involve skill as well as luck to be returned the winner; another object of the invention is to arrange buoyant bodies on submergedl tiltable tracks-there being one buoyant body for each track and these tracks are tiltedl to cause the bodies to submerge and inasmuch as these bodies are buoyant, they will, under the action or' the water, have a natural tendency to rise'to the surface and in their endeavor to rise to the surface, they will be compelled to travel along their respective tracks upon which they are arranged for movement and to which they are connected, use being made of vanti-friction rollers to facilitate the travel of the buoyant bodies; another object of the invention is to produce a device as characterized which embodies track tilting means so that in a case where a plurality of tracks and buoyant bodies are Vin use, these tracks may be actuated singly in the first instance, and unison in the second instance,that is to say, each individual competing shall have to do with his or her own particular track and buoyant body which body, in the present 11istance, is a. minature submarine, whereas the proprietor or conductor of the racehas to do with and takes charge ci, the return of all of the submarines to their normal starting positions, hence the single and s1- multaneous actuationof the tiltable tracks.

In the drawing Figurel is a sectional elevation of the device embodying the present invention.

Fig. 2 is a transverse sectional View taken on the line 2 2 of Fig. 1.

Fig. 3 is a transverse sectional view taken on the line 3-3 of YEig. 1 and looking into the direction as indicated by the arrow.

Referring now t0 the drawing, it will be seen, that use is made of a tank 10 which contains a suitable amount of water. `Arranged within the tank 10 andsubmerged below the surface of the water is a tiltable means 11. y,This tiltable means comprises a track or tracks 12 .which are supported byA arched members 13 which are pivotall mounted 1n bearings 14 lsecured tothe bottom of the tank 10. In order that the tracks 12 may be tilted there is pro-vided tilting means which in the .present instance consists of loop members 15V which are corre@ lated one to each of the tracks 12 and con nected to the upper end of 4each loop mem-v ber 15 there is a flexible element 16 which may be trained over suitable pulleys 17 to bring the `end of the 4members 16 'within reach of an individual competing in the game. Correlated to the en ds of the track- 12, opposite to the ends to which the loop `members. 15 areA correlated,is amember 18y which hasco-nnected to the upper end there- OaiieXible member 19 which is trained over suitable pulleys 20 to bring the end thereof within reach of the proprietor or conductor of the device so that he may cause the simultaneous movement of the tracks 12. Arranged ior movement on each of the tracks 12 is a buoyant boat-like body 21 in the nef.

ture of a minature submarine. Each of these. submarines is correlated'with its respective track by the use of a plurality of members 22v which support "anti-friction rollers 23, the rollers being movable along the opposite edges of the track.

v In practice, the submarines 21 are dis-l posed-all of them-at one end of the tank 10 upon the elevated ends of the tracks 12. The signal tosta-rt is then given, when each individual competing pulls on the flexible member 1b thereby causing the end X of the track to which the saine is correlated by the loopmember 15 to yopposite end Y ol' the track to lower, therebycausing the submarine 21 to submerge and under action of the water and inasmuch as the submarine is a buoyant body, the same to be caused as it tries to rise to the surface of the water to move along the track 12 this being true as regards each of the other submarines 21 in the race and the first submarine to reach the inishing point will be returnedv the winner. Certain indicating mechanism may be' employed to indicate the winner of the race and said indicating mechanism may be actuated by the impact of thev movable sub-V marine inasmuch as they will be of considerable weight and movable in a tank oi' considerable size. By virtue of the pull member and the member 19 the elevation of the ends Y of the tracks l2, and the lowering of the ends X thereof vmay be elected in unison, withthe result that the submarines 2l will be returned to their starting points. The side of the tank 10 arranged nearest the coinpeting individuals may embody a glass panel so that such individuals may view the submarines as they progress along the courses. y It is tovbe understood that no'limitation is necessarily made to the precise showing herein made, but that changes and modifica tions within the scope of the claims may be resorted to when desired.
